10 Under-the-Radar Cybersecurity Threats SMBs Face in 2024 (And How to Defend Against Them)

In the digital age, cybersecurity is no longer just a concern for large corporations. Small and medium-sized businesses (SMBs) are increasingly becoming targets for cybercriminals. While headline-grabbing attacks often target large organizations, SMBs are often overlooked, making them prime targets for less sophisticated but equally devastating attacks. This article will delve into 10 under-the-radar cybersecurity threats that SMBs should be aware of in 2024 and provide practical strategies to defend against them.

Why SMBs Are Attractive Targets

Several factors make SMBs appealing targets for cybercriminals:

Limited Resources: SMBs often have fewer resources dedicated to cybersecurity, making them easier to exploit.
Lack of Awareness: SMBs may not be as well-informed about emerging threats and best practices.
Data Value: While SMBs may not hold vast amounts of data like large corporations, they often possess sensitive information like customer data, financial records, and intellectual property that can be valuable to attackers.
"Easy Targets": Cybercriminals see SMBs as "low-hanging fruit," with fewer security measures in place compared to larger organizations.

10 Under-the-Radar Cybersecurity Threats SMBs Face

Here are 10 cybersecurity threats that often fly under the radar, targeting SMBs in 2024:

1. Supply Chain Attacks

Supply chain attacks exploit vulnerabilities in the software or hardware used by an organization's suppliers. Attackers can infiltrate the supply chain through compromised software updates, malicious code in hardware components, or even phishing emails targeting suppliers.

Defense Strategies:

Vet Suppliers: Carefully select suppliers with strong cybersecurity practices and due diligence.
Software Patching: Ensure all software, including that from suppliers, is regularly patched and updated.
Multi-Factor Authentication (MFA): Implement MFA for all supplier access points.
Security Awareness Training: Train employees on identifying and reporting suspicious emails and activity related to suppliers.

2. Social Engineering Attacks

Social engineering attacks involve manipulating people into giving up sensitive information or granting access to systems. These attacks often use phishing emails, phone calls, or even social media to build trust and trick victims.

Defense Strategies:

Employee Training: Train employees to recognize phishing emails, social engineering tactics, and suspicious communication.
Strong Passwords and MFA: Encourage strong passwords and use MFA for all sensitive accounts.
Security Awareness Campaigns: Regularly conduct security awareness campaigns to keep employees informed about evolving threats.
Phishing Simulations: Conduct periodic phishing simulations to assess employee awareness and identify vulnerabilities.

3. Mobile Device Vulnerabilities

As more SMBs adopt mobile devices for work, they become potential attack vectors. Mobile devices are often less secure than traditional computers, and employees may download apps from untrusted sources or neglect security updates.

Defense Strategies:

Mobile Device Management (MDM): Implement MDM software to control access, enforce security policies, and manage mobile device deployments.
App Security: Only download apps from trusted sources like the official app stores and keep apps updated.
Data Encryption: Encrypt sensitive data on mobile devices to prevent unauthorized access even if the device is lost or stolen.
VPN Use: Encourage employees to use a VPN when connecting to public Wi-Fi networks.

4. Insider Threats

Insider threats can be just as dangerous as external attacks. Employees, contractors, or former employees with access to sensitive information can intentionally or unintentionally compromise the organization's security.

Defense Strategies:

Employee Background Checks: Conduct thorough background checks on all employees and contractors.
Least Privilege Principle: Grant employees only the access they need to perform their jobs.
Security Awareness Training: Educate employees on recognizing and reporting suspicious behavior, data breaches, and unauthorized access.
Data Loss Prevention (DLP): Implement DLP software to monitor and control sensitive data movement within the organization.

5. IoT Device Vulnerabilities

The Internet of Things (IoT) is growing rapidly, and many SMBs are using smart devices, connected appliances, and other IoT systems. These devices often have weak security vulnerabilities, making them easy targets for attackers.

Defense Strategies:

Secure IoT Devices: Choose IoT devices with strong security features, such as encryption, secure passwords, and regular updates.
Isolate IoT Networks: Isolate IoT devices from the main business network to limit the impact of a breach.
Change Default Passwords: Change default passwords for all IoT devices and use strong, unique passwords.
Keep Devices Updated: Regularly update firmware and software for all IoT devices to address vulnerabilities.

6. Cloud Service Misconfigurations

SMBs increasingly rely on cloud services for storage, collaboration, and other business functions. Misconfigurations in cloud services, such as inadequate access controls, weak password policies, or insecure network settings, can expose sensitive data and open the door to attackers.

Defense Strategies:

Cloud Security Posture Management (CSPM): Use CSPM tools to automatically identify and remediate cloud misconfigurations.
Cloud Access Control Lists (ACLs): Implement strict access control lists to restrict access to cloud resources.
Security Best Practices: Ensure cloud service providers follow industry-standard security best practices.
Regular Audits: Conduct regular audits of cloud configurations to identify and address security vulnerabilities.

7. Ransomware Attacks

Ransomware attacks have become increasingly common, with attackers encrypting data and demanding payment to restore access. SMBs are often targeted because they may not have robust backup systems or security measures in place.

Defense Strategies:

Regular Backups: Implement regular data backups and store backups offline or in a secure cloud environment.
Employee Training: Educate employees on identifying phishing emails and suspicious attachments that could lead to ransomware infections.
Endpoint Security: Use endpoint security software to detect and prevent ransomware attacks.
Network Segmentation: Isolate critical systems from the general network to limit the spread of ransomware.

8. Unpatched Software Vulnerabilities

Many software programs, including operating systems, applications, and web browsers, contain vulnerabilities that attackers can exploit. These vulnerabilities often remain unpatched for extended periods, leaving systems exposed to attack.

Defense Strategies:

Regular Patching: Implement a process for promptly patching all software vulnerabilities as soon as updates are released.
Vulnerability Scanning: Use vulnerability scanning tools to identify and prioritize software vulnerabilities.
Patch Management: Centralize patch management to ensure all devices and systems are updated consistently.
Software Inventory: Maintain an inventory of all software used within the organization to track vulnerabilities.

9. Weak Password Practices

Using weak passwords or reusing passwords across multiple accounts is a common mistake that leaves SMBs vulnerable. Attackers can easily guess weak passwords or use stolen credentials from other compromised accounts to gain access to systems.

Defense Strategies:

Password Policy Enforcement: Implement a strict password policy that requires strong passwords, regular changes, and password complexity.
Password Management Tools: Use password management tools to generate and store strong, unique passwords for each account.
MFA: Implement MFA for all sensitive accounts to add an extra layer of security.
Employee Education: Train employees on the importance of strong password practices and password security.

10. Lack of Incident Response Plan

A crucial part of cybersecurity is having a plan for handling security incidents. Without a well-defined incident response plan, SMBs can struggle to contain breaches, recover data, and mitigate damage.

Defense Strategies:

Develop Incident Response Plan: Create a detailed incident response plan outlining steps for detecting, containing, and recovering from security incidents.
Test Incident Response Plan: Regularly test the incident response plan with simulated attacks or scenarios to identify and address weaknesses.
Identify Key Stakeholders: Clearly define roles and responsibilities for key stakeholders involved in incident response.
Establish Communication Channels: Establish clear communication channels for internal and external stakeholders during incidents.

Protecting SMBs from Under-the-Radar Threats
